One of the healthiest trends in Mesoamerican studies in the past two or thee decades has been the recognition that the pre-Columbian cultures of west Mexico were full participants in the Mesoamerican world-system. Long past are the days when west Mexico was excluded from consideration as part of Mesoamerica because of seemingly exotic features such as shaft tombs and round pyramids. Another problem that distanced west Mexico conceptually from greater Mesoamerica was the lack of good chronologies which precluded an understanding of interaction between west and central Mexico. In the introduction to another recent special section, more extensive comments were offered on the history of research in west Mexican archaeology and especially the tension between the fascination with the exotic and the need to develop archaeological research programs based on both chronological and anthropological concerns (Fowler et al. 2006).
